Greetings Circleville Ohio from your Computer Repair specialist
What sort of Computer Repair Service do you want?
The first thing you need to make sure of is that the technician or engineer is actually experienced in your particular machine.
Is your machine a Dell, HP, Apple, or something else?
Is your machine running Apple, Microsoft, or Linux, and which versions?
Is your PC a desktop, laptop, netbook?
Do you have a wired or wireless network?
If you've got problems with internet access; who is your provider, and what make is your router?
If you are a company; what size is your server and what software is it running?
So FIRST: Making sure you know what you have got, will help you decide what sort of service you need.
How do you find reliable computer repair service?
Most companies will tell you on their website about the experience or qualifications they have, and you should look out for the names of your machines or the names of your software.
You should also look out for references from companies that have used the IT company. Ring that company up, and ask about their experience.
How reliable is the repairer?
Do they attend when they say they will?
Do problems get sorted first visit, or after repeated visits?
Do they conduct routine maintenance to prevent future problems?
What's the best, and worst, thing about the IT company?
Would they recommend them?
